Could not connect to Couchbase Bucket

[alexandvo]

I'm trying to use the load command to load documents into my couchbase community server node that is deployed on my local machine. I am not using any containers or vms, I just set up the a single node inside a cluster on my local machine using Couchbase's Community Server installer. It is Couchbase Community Server version 7.6.1 on Windows. I have tested manually creating a document to my bucket on my cluster by using their Python SDK and it works fine. It successfully adds a document to the bucket.

My Config:
I have a single bucket named: test
I have a cluster named: cluster
I have one server on this cluster running on my local machine
I have an admin user with the following credentials:
username: test
password: password

The YCSB load command I used while in the ycsb-0.17.0 directory in my local machine:
bin/ycsb load couchbase2 -s -P workloads/workloada -p couchbase.bucket=test -p couchbase.password=password -p recordcount=1000

I saw a previous issue talking about a similar problem where it was solved by making the admin account have the same name as the bucket to insert to, but I still have the issue even after doing this.

After executing this command it doesn't make any inserts to my cluster and it outputs that it did 0 operations...

Here is the full output with the errors after I execute this load command:

Hi @alexandvo feel free to have a look at our YCSB result files which include the CLI parameters: https://github.com/benchANT/database-ranking/tree/main/CRUD-general-purpose/2022/ranking_batch-0_couchbase-ce-xsmall-small_0_ZoCTfpqe

They were run with the YCSB Client 0.17.0 using the Couchbase2 binding against Couchbase CE 7.0.0 and it should also work against CE 7.6

Thank you for providing me with your YCSB result files. I recently get passed connecting to the node and the bucket I think since it now says: "INFO: Connected to Node 3.90.221.18
Jul 12, 2024 6:44:19 PM com.couchbase.client.core.config.DefaultConfigurationProvider$8 call
INFO: Opened bucket couch" but it throws a new error saying "Request cancelled in-flight" and this occurs when I used a similar load command as the one y'all used for your benchmarking of couchbase in ec2 large. The only things I changed were bucket name, username, password, and host. This error also occurs with the basic load command as follows: bin/ycsb load couchbase2 -s -P workloads/workloada -p couchbase.host= -p couchbase.bucket=couch -p couchbase.user=couch -p couchbase.password=password. Did you ever run into this issue of request being cancelled in-flight? If so, how did you solve it? Here is the full error by the way: YCSB Client 0.17.0

I've got the same error with Couchbase 7.6, when, with same setup, with any other couchbase server version it is working fine. Could you please check this?

Connected to node, connected to bucket, but then:

@lpankaz are you using the 0.17.0 or the 0.18.0-SNAPSHOT of the YCSB?

Both versions use the Couchbase2 binding which is unfortunately not compatible withe Couchbase 7.6.

You would need the couchbase3 binding which is available on the [Couchbase YCSB](https://github.com/couchbaselabs/ycsb-couchbase/tree/main/core) fork or the benchANT fork.

We recently did several benchmarks against Couchbase 7.6 using the benchANT fork and it worked without a problem.

[lpankaz]

@seybi87 thanks for sharing ycsb-couchbase, that will work for me! :)

Yup, I just thought that maybe here in main repo we'll get couchbase3 binding.
